The adapter supports Ethernet communication rates from 10 Mbps to 100 Mbps with half-duplex and full-duplex operation modes.\u003c\/p\u003e\n\u003cp\u003eThe module is designed for PowerFlex drive installations requiring external network access without direct modification of the drive control hardware. Its DPI connector provides the internal communication path to compatible drive platforms, while the RJ45 interface provides Ethernet network connectivity.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What is the power source for the 22-COMM-M communication adapter?\u003cbr\u003eA: The adapter receives operating power from the connected host drive or DPI External Communication Kit. The specified drive electrical consumption is 350 mA at 5 VDC.\u003c\/p\u003e\n\u003cp\u003eQ: Does the 22-COMM-M require an external network power supply?\u003cbr\u003eA: No. The network electrical consumption is specified as none. The module receives power through the host DPI interface connection.\u003c\/p\u003e\n\u003cp\u003eQ: What communication connections are supported by the adapter?\u003cbr\u003eA: The adapter supports up to 30 TCP connections, including up to 16 simultaneous CIP messaging connections and one Modbus\/TCP I\/O connection.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cp\u003eInstall the 22-COMM-M adapter inside the compatible PowerFlex drive or approved DPI communication enclosure according to the drive hardware installation procedure.\u003c\/p\u003e\n\u003cp\u003eConnect the DPI interface firmly to the designated drive communication connector before applying power. Use shielded Ethernet cabling for the RJ45 network connection where required by the industrial environment. Maintain separation between communication wiring and high-voltage power conductors to reduce electromagnetic interference.\u003c\/p\u003e\n\u003cp\u003eVerify that the adapter LEDs indicate normal DPI, adapter, and network communication status after installation. Confirm firmware compatibility between the communication adapter and the connected PowerFlex drive before commissioning network communication functions.\u003c\/p\u003e\n\u003cp\u003eFor panel-mounted installations, maintain the enclosure protection rating requirements and ensure proper grounding of metallic mounting structures and cable shields according to site electrical standards.\u003c\/p\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":43796508344410,"sku":"20-COMM-M","price":123.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0612\/4601\/3530\/files\/20-COMM-M2.jpg?v=1786074460","url":"https:\/\/www.plcmasters.com\/products\/allen-bradley-22-comm-m-modbus-tcp-communication-adapter","provider":"PLC Masters Ltd.","version":"1.0","type":"link"}
